Summary:

By applying large top land gaps bore polishing can be reduced significantly or avoided entirely. Lube oil consumption is also reduced and remains constant over a long period of time. By means of a suitable lay out of the piston and a minimizing of the air volume in the top land gap, the fuel consumption can even be reduced somewhat versus the standard piston version. With a minor correction of the fuel injection timing the same U.S. 13-mode-cycle emission values of HC and NO\dx as with the standard piston can be obtained without any deterioration of the fuel consumption versus the standard version
